ABSTRACT
We shall begin by assuming the conventional objective testing procedure in which the person is presented with a number of items to be answered. Each answer is scored as correct or incorrect, and a simple or a weighted sum of the correct answers is taken as the test score. The various procedures for determining which items to use and the best weighting methods will be considered later. For the present we assume that the numerical score is based on a count, one or more points for each correct answer and zero for each incorrect answer, and we turn our attention to the determination of the accuracy of this score.
